Photobiomodulation

Photobiomodulation therapy, also known as low-level laser therapy or cold laser therapy, is a treatment that applies low power lasers or light emitting diodes to the surface of the body to trigger a photochemical reaction in tissue without causing heat damage. Practitioners use it with the aim of stimulating healing, reducing pain and improving cell function, and a number of photobiomodulation devices have received clearance from the United States Food and Drug Administration. Research into its effectiveness is ongoing and the quality of evidence varies by condition, but studies have examined potential benefits for conditions including juvenile myopia, rheumatoid arthritis and oral mucositis.
